We all wear different styles of cloth in our daily life. And all those clothes materials will include different fabrics. Either it is a synthetic fibre, natural fiber, or polymer. So always it becomes a concern how they differ from each other?
Fibre:
What is fibre? Isn't it the material which is used in clothes? Or what is it?
- Fibre is the only material that helps in the development of fabric.
- And this fabric also designs the home things.
Polymer:
The word 'Polymer' consists of two words, I.e., Poly(many) +mer(unit).
- It includes many units.
- And it is also known as a larger unit. Further, which helps in making the 'fibre & fabric.'
1. Synthetic Fibre:
Synthetic fibres are human-made fibres. And are:
- Durable
- Easily affordable
- For e.g., Nylon & Rayon
2. Natural Fibre:
Have you heard about fibre coming from animals & plants? Yes, these are among those only!
- e.g.Cotton, silk, and wool.
3. Plastics:
What is plastic? You can define plastic-like. It is only a material that is similar to synthetic fibre.
Thermoplastics:
- Most flexible plastics!
- Ease to bend (it resolve with heating)
Thermosetting plastics:
- Hard plastics!
- Bend only once, i.e., with a one-time heating process only.
